GE restocking is still experimental, sometimes it works really good sometimes a small glitch can mess it up. I am continuously looking for new ways to make it more flawless and stable. As for without coal bag it's a bit faster now with the new update I am currently testing because I made it faster and reduced multiple delays in the script wherever I found fit
Stamina potions - I will make a custom range for it in the setup window just like my runecrafting script. (perhaps even a condition).
Thanks guys, more info and updates coming soon
